BOOT-TREE.

SPECIFICATION forming part of Letters Patent No. 395,7 53, dated January8, 1889.

Application filed May 29, 1888. Serial No. 275,446. (No model.)

To all whom it may concern- Be it known that I, ALFRED M. MOORE, ofMalden, in the county of Middlesex, State of Massachusetts, haveinvented a certain new and useful Improvement in Boot-Trees, of whichthe following is a description sufficiently full, clear, and exact toenable any person skilled in the art or science to which said inventionappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in whichFigure l. is a side elevation of my improved boot-tree, a portion of thebody being broken away to show the interior; Fig. 2, a top plan view ofthe leg portion; Fig. 3, a bottom plan view; Fig. 4, afront elevation,the foot portion being removed; and Fig. 5, a rear elevation of the footportion.

Like letters and figures of reference indicate corresponding parts inthe diflferent figures of the drawin My invention relates especially tothat class of boot-trees which are en'iployed in. the man ufacture ofrubber boots; and it consists in certain novel features, as hereinafterfully set forth and claimed, the object beingto produce a more effectiveand otherwise desirable device of this character than is now in ordinaryuse.

The nature and operation'of the improve ment will be readily understoodby all conversant with such matters from the following explanation Inthe drawings, A represents the leg por-' tion, and B the tootpiece, ofthe tree, these parts being constructedhollow and separable and composedof a compound of wood fiber, papierqnach, or similar material.

The leg A is provided with a centrally-arranged Vertical standard, E,having a vertically-arranged dovetail-groove, G, on the side next thefoot-piece. The standard is provided at its top with two laterall y-projectin g arms or braces, I), (see Fig. 4,) which are secured to the sidesof the leg-piece by rivets t, and serve to assist in keeping saidstandard in position. The upper portion of the standard E is providedcentrally with a hole or socket, 2', (see Fig. 1,) adapted to receivethe lower end of the clamping-bar O, hereinafter described.

The foot-piece B is provided interiorly with a brace, D, having twot'orwardly-projecting arms, fg, which are respectively secured to theinstep and sole portions thereof byrivets m, as shown in Fig. l. Thebrace D is also provided on its upper portion with laterallyprojectingarms or braces d, (see Fig. 5,) secured by rivets to the sides of saidfoot-piece and designed to assist in keeping said brace in position. Adovetail, F, fitted to slide in the dovetail groove G of the standard E,is formed on the rear of the brace D.

The red O is provided at its upper end with a handle, a, and disposed onsaid rod near said handle is a lateral brace, H, havingdownwardly-projecting armsj secured to the sides of theleg A by rivets7t, and a hub, 03, on its under side, through which i said rod passes.The red O passes through a circular hole, 2, in the hub 92, into whichopens a laterally-arranged slot, it. (See Figs. 1 and Anupwardly-projectin fiat spring, 71 is secured to the red O and passesthrough the hole .2, said spring being adapted to enter the slot to inthe hub 00 and prevent said rod from turning therein.

The lower end of the rod O is provided-with a laterally projectinginclined flange, 19, adapted to be turned under a locking-cam, q, on thebrace D of the toot-piece and lock said piece to the leg portion.

In the use of my improvement the footpiece 13 is first inserted in thefoot portion of the boot to be treed. The leg portion A is then insertedin the leg of the boot, the parts being so arranged that the dovetail Fwill enterthe groove Or, when, by revolving the rod C, the flange 1)will pass under the lockingcam g on the brace D of the foot-piece, thespring 71 at the same time entering the slot w in the brace H, thusfirmly locking the leg portion and foot-piece together and preventingthem from becoming accidentally unfastened. To remove the tree from theboot, the spring 7L is forced back against the rod O until it is freefrom the slot w, said rod being then turned until the flange 19 passesfrom 1111* der the cam q, when the legA maybe detached from thefoot-piece and both Withdrawn from the boot in a manner that will bereadily understood by all conversant With such matters Without a moreexplicit description.

Having thus explained my invention, what I claim is 1. In a boot-tree,the combination of a hollow leg portion, a centrally-disposed verticalstandard secured in the bottom of said leg portion and provided in itsouter face with a dovetail groove, a vertically-arranged lockingrodprovided With a flange near its lower end, said rod being journaled inthe top of said standard and in a brace in said leg portion,a foot-pieceprovided with a brace having a dovetail adapted to enter said dovetailgroove, and a locking-cam on said brace adapted to engage the flange on,said rod and thereby secure said leg portion to said foot-piece,substantially as set forth.

2. In a boot-tree, the combination of a hollow leg portion, acentrally-disposed vertical standard secured in the bottom of said legportion and provided in its outer face with a dovetail groove, avertically-arran ged locking; rod provided with a flange near its lowerend, said rod being journaled in the top of said standard and in a bracein said leg portion, a

foot-piece provided with a brace having a dovetail adapted to enter saiddovetail groove,

a locking-cam on said brace adapted to engage the flange on said rod,and thereby secure said leg portion to said foot-piece, and a spring onsaid rod adapted to enter a slot in the brace in said leg portion andkeep the rod from turning, whereby said cam and flange are preventedfrom becoming accidentally disengaged, substantially as described.

3. In a boot-tree, the combination of theleg A, the standard E, providedwith the dovetail groove G, hole 2', and arms d, the brace H, providedwith the hole 2 and slot 10, the lockingrod 0, provided with the flange10 and journaled to revolve in the holes '6 z, the spring h, secured tosaid rod and adapted to enter the slot 10 and prevent said rod fromrevolving,

the foot-piece B, the brace D, secured in said foot-piece and providedwith the dovetail F, adapted to enter said dovetail groove, and thelocking-cam g on said brace, said cam being adapted to engage the flangep and secure said foot-piece to said leg portion, substantially as setforth.
